To aZZ whom it may concern:

Be it known thatl, SAMUEL D. BARR, acitizen of the United States,residing at Minerva, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Flour-Bolts; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters of referencemarked thereon, in which- Figure 1, is a side elevation, showing partsbroken away to illustrate the position of the reel and its differentparts. Fig. 2, is a top view, showing the top or cover removed andillustrating portions of the bolting cloth removed or broken away. Fig.3, is a transverse section through line w-x Fig. 2 except that the coveris shown placed in proper positlon in .this figure. Fig. 4, is adetached view of the stock feeding hopper. Fig. 5, is a detached view ofthe delivery end of the reel. Fig. 6, is a transverse section of one ofthe valves or separating blades. Fig. 7, is an enlarged view of thesweepblade, illustrating its position with reference to the periphery ofthe reel proper. Fig. 8, is a detachedview of the sweep-blade. Fig. 9 isa longitudinal vertical section. Fig. 10 is an end view, showmg the rearend of the reel frame.

The present invention has relation to flour bolts, and it consists inthe different parts, and combination of parts hereinafter described andparticularly pointed out in the claims.

Similar letters of reference, indicate corresponding parts in all thefigures of the drawings.

The object of the present invention is to provide a-fiour bolt and meansfor removing all of the flour and the difierent separations of wheat orstock, from the boltproper, thereby leaving all of the different partsof the bolting machinery clean, and free from flour at the end of a run.With this object in view it will be understood that no flour is allowedto accumulate and become musty, and impregnated with worms to be mingledwith the new flour at the beginning of a new run.

Afurther object of the present invention is to provide a means forconveying from the reel proper the finished flour and the differentgrades separated from the stock.

In the accompanying drawings Arepresents the frame, which isconstructed-in the ordinary manner, reference being bad to properlyattaching the'different parts belonging to the reel proper. The frame Ais constructed of a size to correspond with the size of the reeldesigned to be used. The shaft to is properly journaled to the frame A,and is provided with the cylinder B, which cylinder may be of the formshown or it may be of any other desired form. Upon the periphery of thecylinder B, are attached the ribs b, which ribs are locatedsubstantially as shown in the drawings. To the ribs 2) are attached thebands 0 said bands being held a short distance away from the ribs in bymeans of the interposed blocks 0 or their equivalents. It will beunderstood that the bands 0 should be covered with cloth for the purposeof preventing injury to the bolting cloth.

For the purpose of holding the disks D and I) in proper position asufficient number of the ribs b are extended a short distance beyond theends of the cylinder B and said disks securely attached in anyconvenient and well known manner.

To the upper or feed end of the cylinder B is attached the funnel (Z,which funnel is located substantially as illustrated in Fig. 2, and asillustrated in said figure, the mouth of said funnel is located a shortdistance away from the inner face of the disk D.

For the purpose of conveying the stock between the cylinder 13, and thebolting cloth D the hopper E is provided, which hopper is located uponthe outer side of the disk D, as

illustrated in Fig. 2. Below the hopper E is located the flange F, whichflange is received into an opening formed in the disk D, said openingbeing shown in Fig. 9.

Forthe purpose of shunting the stock into the funnel d the inclinedplate G is provided, which plate is located, substantially asillustrated in'Fig. at. For the purpose of preventing the stock fromfalling upon the outer side of the disk D, and at the same time forminga cover for the opening d, the hood d is provided, which hood isattached to the inoo cliued plate G. It will be understood that byproviding the funnel d, and feeding the] I cated substantiallyasillustratedin Fig. 7, and

, purpose hereinafter described. Below the cylis preferably formed ofrubber or like material, and as illustrated in Fig. 8 the sweepbladeI isprovided with theelon gated slots e, which elongated slots are for thepurpose of adjusting the sweep-blade to or from the bolting cloth D Uponthe sweep blade I is placed the bar J, which bar is locatedsubstantially as illustrated in Fig. 7, and as shown in said figure itsouter edge is beveled for the inder B and its diiferent parts, islocated the concave bottom K, which concaved bottom is the segmentof acircle having a common center with the center of the cylinder B. Thesweep-blade I is so adjusted that it will sweep the concaved bottom K asit revolves with the cylinder B, together with its different parts. Forthe purpose of causing the sweep-bladeI to drag on the concavedbottoinKsaid sweepblade is inclined downward from a radial line asillustrated in Fig. 7. A further purpose of inclining the sweep-blade I,will hereinafter'be described.

To the delivery side of the concaved bottom K is located the inclinedledge K, which ledge is preferabl concaved upon its upper side asillustrated in Fig. 3. Above the delivery ledge K is located the shaft Kwhich shaft is properly journaled to the frame A, and as shown in Figs.1 and 3 the shaft K is provided with the brushes K which brushes arelocated as illustrated in Figs. 1 and 3. The brushes K are so adjustedthat they will sweep the bolting cloth D A further purpose of thebrushes K is to sweep the sweepblade I.

It will be understood that as the flour is sifted through the boltingcloth D it will fall upon the concaved bottom K, and as the blade Isweeps said concaved bottom it will gather the flour upon the sweepblade I and elevate the same, as the sweep-blade revolves, therebybringing the flour opposite the ledge K. At the time the sweep-blade Ireaches the ledge K the brushes K will sweep the flour from thesweep-blade. For the purpose of causing the brush K to properly act uponthe sweep-blade I the shaft K is so timed that the inner section of saidbrush will strike the sweep-blade as the shaft K revolves; rotary motionbeing communicated to the shaft K and i'tsbrushby means of thesprocketwheel f and the drive chain g. It will be understood that byinclining the sweep-blade I as illustrated in 7 said sweep-blade will beinclined downward toward the ledge K at I the time said sweep-bladereaches said ledge,

thereby bringing said sweep-blade in proper position to be delivered ofits load by means of the brush K It will also be understood, that bybeveling the outer edge of the, bar J the flour will be easily removedfrom said bar. To the side of the ledge K, and below said ledge arelocated any desired number of chambers such as L and L, said chambersbeing for the purpose of receiving the different grades of flour. I I

It will be understood, that after thedift'erent grades of fiour havebeendelivered into the chambers, they are to be conveyed through ordinaryconduits to any desired 'point'or points. In the construction of reelsof considerable length the inclined end of the chamber L wouldnecessarily be less steep or in other words the inclination would not beas great as the inclination in shorter reels.

For the purpose of preventing flour from lodging upon the inclined "endof the chamber L the reciprocating ,board or plate M is provided;reciprocating motion being communicated to the board or plate M-bymeansof the pivoted arm 72., the lever'h, and the 'tappets k 'Itwill beunderstood thatihe weight of the board or plate M will have a tendencyto elevate the inner end or portion of the lever h, thereby holding thatlever in operative contact with the tappets h The object and purpose ofproviding the tappets are I to give to the board or plate M, twodistinct movements to one revolution of the shaft K For the purpose ofgaging the different grades of flour and other divisions of the stockthe valves 70 and 7c are provided, said valves being located in thechambers L and L. For the purpose of holding the valves 70 and 70 at anydesired point of adjustment the edges of said valves, are provided withrubber strips such as 70 which strips are so adjusted that they willpress or bear against the inner sides of the chambers L and L. It willbe understood, that each of the valves k and 70 should be provided withan operative handle such as 70 so as to provide a means for adjustingsaid valves. It will be underderstood that the valves '70 and 7c are tobe pivotally attached at their bottom or lower ends by means of thecross rods 10 In the drawings I have shown but two chambers, and twovalves, so arranged and adjusted that four divisions of the stock -canbe made; but it will be understood that the numberof chambers and valvesmay be increased with out departing from the nature of my invention.

To the disk D is attached the collar N, the inner portion of which iscone shaped as illustrated in Figs. 2 and 5; and as shown the innerportion is provided with the opening 0, to the side of which opening islocated the flange m, said flange being securely attached in anyconvenient manner to the inner-face of the disk D. The object andpurpose of providing the opening 0 and the flange mare to provide ameansfor conveying the tailings or bran to the delivery "spent '21. Itwill be inspecting the inside of the frame and its different parts thedoor 1? is provided, said door being inclined as illustrated in Fig. 3,and is so adjusted that it can be easily removed,

. thereby providing a means for permitting an overflow in case the reelproper should become choked. It will be understood that the pressure ofthe stock upon the inner side of the door will press the door outward,and permit the stock to overflow.

a In Fig. 2 the brush K is not shown, said brush being omitted for thepurpose of better illustrating the position of the sweep-blade, whenit-arrives at the point to be delivered of its load, also showingthelocation of the ledge K. By inclining the sweep-blade I together withthe bars H and J downward from a radial line through the reel, saidparts will be inclined from the bolting cloth toward the ledgeK at thetime said parts are ata point opposite said ledge, thereby bringing thesweep-blade together with its attaching bars in proper position to bedelivered of its load by means of the brush K For the purpose of timingthe brush K the sprocket wheels f are formed of one size, and each isprovidedwith an equal number of teeth, thereby causing the reel andbrush to rotate in unison.

Having fully described my invention, what I claim as new, and desire tosecure by Letters 45 having located therein a revolving reel, the

disks D and D, having fixed thereto the bar H, the sweep-blade I,provided with the elongated slots 6, the beveled barJ, located ad3acentto said sweep-blade, a revolving brush, the ledge K, the chambers as Land L, and valves located in said chambers, substantially as and for thepurpose set forth.

2. The combination of a suitable frame, having located therein arevolving reel, a sweep-blade, located upon the outside of the boltingcloth, the concave bottom K located below the reel, the ledgeK', theshaft K ,provided with the tappets 71. the lever 71. the link h, and theboard or plateM located in a chamber as L, substantially as and for thepurpose set forth.

3. The combination of a frame,a shaft havin g mounted thereon a cylinderprovided with ribs b, the rings 0, the bolting cloth D the disk D, thehopper E- located upon the outside of the disk D, the inclined plate G,located below the hopper, the funnel d, and the flange F extendedthrough the disk D, substantially as and for the purpose specified.

4. The combination of the frame having located therein a revolving reelprovided with a sweeping blade located upon the outside of the boltingcloth, a concave located below the reel, the brush K the ledge Kthe-sprocket wheel f and the drive chain g, substantially as and for thepurpose specified.

In testimonyfthat I claim the above I have hereunto subscribed my namein the presence of two witnesses.
